Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device used for a door of a container, which can be pivoted around a hinge.
Two locking mechanisms are provided which cooperate with one another in a form-fitting manner, the first locking mechanism of the two locking mechanisms being
The tilting lever, which is arranged stationary in the container and is operated by an electromagnet, acts on the tubular lock plunger to bring the first locking mechanism to the unlocked position, and the second locking mechanism. Is configured as a connecting pin having an undercut portion, and the kneading pin is connected to the door.

[0002]

2. Description of the Prior Art A locking device of this type is known from German Utility Model Specification 9100626.

This known locking device consists of an electromagnet with permanent magnets connected in parallel and a tilting lever pivotally supported. The tilting lever is held in a horizontal locking position by a permanent magnet, in which case it holds the tubular locking plunger in a closed position. The lock plunger presses the ball cage via a spring, which pushes the contained ball into the undercut of the connecting pin in a form-fitting manner. The lock plunger provided with the spring, the ball cage and the ball is a part of the first lock mechanism, and the connecting pin provided on the door is the second lock mechanism.

The lock release of this known lock device is performed as follows. That is, when the electromagnet is excited,
The holding force of the permanent magnet is offset. The tilting lever moves away from the pole pieces of the permanent magnet, thereby releasing the lock plunger and thus releasing the ball from engagement with the connecting pin.
The container door is thus unlocked.

The locking is performed in a state where the electromagnet is not excited. In this case, first, the connecting pin is introduced into the first locking mechanism, and the tilting lever is crimped to the pole piece of the permanent magnet by using a tool from the outside. To be done. At this time, the ball engages with the undercut portion of the connecting pin, and the door is locked.

The known locking device has the following drawbacks. That is, the position adjustability between the first lock mechanism and the second lock mechanism is not set, and a manufacturing error between the door and the container causes a difference between the container and the first lock mechanism. It can only be compensated by placing spacer plates. Since the locking device is usually installed inside the container, such position adjustment is time-consuming and expensive.

The container with the emergency breathing system described in US Pat. No. 4,023,874 is closed by a door which is pivotable about a hinge. A connecting pin is fixed to the door as a second lock mechanism, and the first lock mechanism is attached to the container. This first
The locking mechanism is adapted to formally engage the connecting pin when the door is swung closed. This known container has the following drawbacks. That is, when the door is closed, the locking device is inaccessible and therefore it is difficult to later align the door to be flush with the adjacent fixed plate.

A container with an emergency breathing system, disclosed in US Pat. No. 2,934,293, is closable by a door that is pivotable about a hinge,
It has a first locking mechanism provided on the container wall. This first locking mechanism projects into the inner chamber of the container. Further, the container has a second locking mechanism provided inside the door.

The known container has the following drawbacks. That is, the first locking mechanism is mounted on a separate fixed rail outside the registration range of the door, thus making this structure unsuitable for modular container storage systems. The position adjustment of both locking mechanisms is possible only conditionally, that is to say by loosening the fixing nut in the center of the first locking mechanism and then sliding it by hand. Since such means must be performed with the containers assembled, it takes a great deal of time to perform the position adjustment when the number of containers is large.

[0010]

SUMMARY OF THE INVENTION The object of the invention is to improve a locking device of the type mentioned at the outset to provide a locking device which allows a simple adjustment of the position of the container relative to the door. .

[0011]

In order to solve this problem, according to the structure of the present invention, the first locking mechanism is integrally formed on the container in the alignment range of the door, and is parallel to the door. Is fixed to the door so that the effective length of the connecting pin can be adjusted on the pin holding device whose position is variable with respect to the door within the engagement range of the first locking mechanism. Between the container and the door by means of a position adjusting tool which has a first adjusting element at the end of the head and which can be introduced into the lock plunger from the tilting lever side through the first adjusting element. The plunge depth of the connecting pin into the first locking mechanism, which regulates the play of, can be changed.

[0012]

The advantages of the present invention are mainly as follows.
That is, the locking device mounted on the container in the alignment range of the door has a connection pin with a first adjusting element with an adjustable effective length. The first adjusting element can be operated by means of a position adjusting tool which can be introduced into the lock plunger, in which case the penetration depth of the connecting pin into the first locking mechanism can be adjusted. This allows the length of the connecting pin to be varied even when the door is locked, until the play that may be present between the door and the container is compensated, for example due to manufacturing errors. The plunge depth means the length of the connecting pin with respect to the first lock mechanism. If the plunge depth is too large, there will be play between the door and the container. On the other hand, if the plunge depth is too small, the form-locking cooperation of the two locking mechanisms is no longer possible and the door can no longer be locked. In order to realize changing the length of the connecting pin, the shaft part of the connecting pin is equipped with a threaded pin, and this threaded pin corresponds to the thread of the pin holding device provided on the door. It can be screwed into the attached housing. The first adjusting element provided at the head end of the connecting pin is, for example, a slit or a hexagonal hole, and the position adjusting tool is a driver or a hexagonal wrench. The connecting pin may be divided into two parts, in which case the connecting pin consists of a spherical head end and a threaded shank which is provided on the pin holding device. It is inserted in the fixed cylindrical part. For the purpose of mounting the locking device according to the invention, the container is at the container edge opposite the hinge,
It is machined so as to give rise to a parallel mounting plane which comes into contact with the door, to which the locking device is fixed. In the region of the connecting pin, the linking pin can directly engage the first locking mechanism, since the mounting plane is provided with holes. Advantageously, the mounting plane is provided on the container in the alignment range of the door and the locking device is located outside the container. If the locking device is located inside the container, at the bottom of the container,
Adjustment holes must be provided for the introduction of alignment tools. Based on such a combination of the container and the locking device, the doors are adjusted in position outside the assembly point without disassembling the components beforehand, and then the adjusted system is used to store the container in the aircraft. It can be inserted into the system.

In a further advantageous configuration of the invention, a second adjusting element is provided in the area of the pin holding device instead of the first adjusting element or in addition to the first adjusting element. To the first locking mechanism, which defines a play between the container and the door by means of a positioning tool which can be introduced through the second adjusting element through an adjusting hole provided in the door. The plunge depth of the connecting pin can be changed. The second adjusting element may be constructed identically to the first adjusting element. Second
With the adjusting element of No. 2, the position of the connecting pin can be adjusted from the side of the door surface.

It is advantageous if the threads of the connecting pin are of a detent type and that the connecting pin is inserted in a star-shaped pin-holding device, for example made of plastic. The pin holder is slidably housed in the door in a U-shaped member, which ensures self-centering of the connecting pin when the door is closed. Detent threads are threads that are prevented from automatically returning, i.e., loosening, for example by using friction.

In order to reduce the friction between the pin holding device and the door or the U-shaped holding member, it is advantageous if the star-shaped leg ends are designed spherically.

The pin holding device is non-rotatably attached to a U-shaped holding member provided on the door. This relative rotation prevention is such that when the rotation is about to occur, the leg end portion is U-shaped.
It can be realized by being locked by the letter-shaped holding member. Due to the non-rotatable mounting of the pin holder, the adjustment of the connecting pin with the position adjustment tool is improved.

The tilting lever is advantageously operated by the door when closed. In this case, the first locking mechanism is brought to the closed position and the tilting lever is held in this position by the holding force of the permanent magnet.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows a container 1 with a door 3 for swiveling around a hinge 2 for housing an emergency breathing system 4. FIG. 1 shows the open position, in which the emergency breathing system 4 is ready for use. In the preparatory stage, the door 3 is held in the closed position by the locking device. This locking device consists of two locking mechanisms which cooperate in a form-fitting manner. Two
Of the two locking mechanisms, the first locking mechanism 5 is arranged outside the container 1 in a stationary manner on an assembly plane 6 integrally molded with the container 1, and the second locking mechanism is combined with the door 3. Configured as the connected pin 7. The first lock mechanism 5 is located in the alignment range of the door 3. The emergency breathing system 4 is placed in the container in a folded state during the preparation phase. The emergency breathing system mainly comprises a cartridge 8 for generating oxygen, a hose 9 and a breathing mask 10.

In FIG. 2, the container shown in FIG.
There is shown a view, viewed in the direction of arrow A, taken in section along with, in which case the closed position with the door 3 is shown.
The same components as those in FIG. 1 are indicated by the same reference numerals as those in FIG. The first lock mechanism 5 has a casing 12 having a cylindrical hole for the lock plunger 13 and a housing portion for housing the electromagnet 14. The electromagnet is fitted on a U-shaped bent pole piece 15,
A permanent magnet 16 is provided on the left leg 151 of the pole piece 15. The electromagnet 14 and the permanent magnet 16 are connected in series with respect to the magnetic flux, but the magnetic flux directions are opposite to each other. The magnetic flux is closed by the plate 17 mounted on the pole piece 15. The plate 17 is fixed to a tilting lever 18, and the tilting lever is rotatably supported by a joint 19 provided in the casing 12. The tilt lever 18 holds the lock plunger 13 in the closed position by means of a projection 20.

Inside the lock plunger 13, the spring 2 is

Of these, only one ball is shown in FIG.
The first locking mechanism 5 is fixed to the assembly plane 6 using fixing screws. Facing the mounting plane 6 a part of the door 3 is located, which has a U-shaped holding member 24 for a pin holding device 25 with a threaded spherical connecting pin 7. ing. The pin holding device 25 is mounted inside the U-shaped holding member 24 so as to be slidable but not relatively rotatable. The connecting pin 7 is slidable inside a centering hole 26 provided in the engagement area of the first locking mechanism 5 and has a first adjusting element 27 in the form of a slit.
have. The lock plunger 13 is a position adjusting tube 28.
As a result, the first adjusting element 27 is accessible from the outside, that is, from the tilting lever 18 side. In the area of the position adjusting tube 28, the tilting lever 18 is guided as an eye 29 so as to surround the position adjusting tube 28.
In the position shown in FIG. 2, the ball 23 is engaged with the undercut portion provided on the connecting pin 7, and thus the door 3 is locked. The tilt lever 18 is the plate 1
